The super middleweight posted a video of himself back in the gym on Sunday, working out ahead of his next challenge.

It capped an eventful weekend for the Briton, who wasn't put off by the hostile scenes inside the Hanns-Martin-Schleyer Halle.

Shortly before Eubank Jr. was due to walk out for his bout with Yilidirim, two gangs -- reportedly from Turkey and Albania -- brawled ringside with as many as 50 men involved.

But the raucous crowd were left speechless after Eubank Jr.'s left hook that sent Yilidrim to the canvas.

The location for Eubank Jr.'s next bout is to be confirmed, but should Groves prevail on Saturday the WBSS promoters could consider holding the bout at Stamford Bridge -- home of Chelsea Football Club -- or Wembley Arena.

London-born Groves is understood to be a Blues fan, although the weather in January could put pay to the idea.
